P 1947. W.-T. HORMES I MOUNTING FOR SLIDING D OOR FRAMES Filed Aug. 25,1944 Patented Sept. 30, 1947 UNITED. STATES PATENT OFFICE MOUNTING FORSLIDING DOOR FRAMES William T. Hormes, Catonsville, Md. ApplicationAugust 25, 1944, Serial No. 551,167

This invention pertains to store-furniture cabinet unit containers ofthe type in which slidingly mounted glass doors are arranged to closethe front of a unit. Such a unit container is illustrated and describedin a pending application filed August 20, 1942, Serial No. 455,481 whichhas become Patent No. 2,367,124, dated Jan. 9, 1945, to which referenceis made for purposes of illustration only.

One of the objects of the invention is to provide Simple and effectivemeans for releasably mounting a door-supporting frame within astore-furniture unit container which is to be equipped with slidingdoors, A further object is to provide a door-frame mounting of thecharacter mentioned by means of which the frame may be verticallyadjusted within said unit, after the frame and its mounting have beeninstalled. A further object is to provide a door-frame mounting of thecharacter mentioned by means of which the position of the frame may beso adjusted as to bring its front face in alignment with the front edgesof the end walls of the cabinet unit container. Another object is toprovide a door-frame mounting which may be quickly installed or removedat will, with a minimum expenditure of time and labor.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings:

Referring to the drawing C designates a storefurniture cabinet unitcontainer which may be of any desired or well known construction. Astore furniture cabinet C of the character disclosed and claimed in aco-pending application Serial No. 455,481, has been selected forpurposes of illustration and without intent to limit the invention inthis particular, As shown in the pres- 8 Claims. (01. 312-189) entdrawing, the cabinet C is provided with a base lo, a top H, two ends l2,and a back 13, all assembled to provide a complete cabinet structureopen at the front. Unit container inserts are preferably removablypositioned within the cabinet C, and are normally retained therein bymolding strips M removably attached to the front edges of the end walls[2, in a manner not shown in detail in the present drawing, but fullyshown and described in the above identified application, to whichreference is hereby made. The end walls l2 are provided with verticalchannels M in which are located slotted strips l5 for receivingremovable lugs to support shelving. These strips and lugs may be of anydesired construction, but

it is preferred to employ the arrangement illustrated in a copendingapplication filed August 20, 1942, Serial No. 458,480.

Two doors D are mounted in overlapped sliding relation within adoor-carrying frame F which is positioned adjacent the front of thecabinet C. Said frame is constructed with two parallel channels l6,Ilia, one for each door, and arranged to provide a rectangular structureof proper dimensions to be inserted into the front of the cabinet. Theframe F is adjustably mounted within the cabinet by mountings A whichare connected to opposite vertical sides of the frame.

Each frame mounting A consists of a supporting plate 20 which isprovided at one end with oppositely disposed ears 2|, having screwthreaded openings 22 therein, said ears being joined to the edges of theplate by reenforcing flanges 23. The lower edge of said plate contiguousto the other end thereof is provided with a plurality of horizontallyspaced notches 24, positioned to selectively register with a slottedstrip l5, and to be engaged by a lug 25, which may be selectively andreleasably engaged with any of the slots in said strip. Fixedly attachedto opposite sides of the frame F and to the inner surfaces thereof, areframe-carrier members 21, each provided with oppositely disposed cars28, having opening 29 which are positioned to register with the openings22 of the plate 20. Rotatively mounted in the openings 29 are thereduced ends 30 of a screw threaded rod 3|, the threads of which engagethe threads of said openings 22, The reduced ends 30 of said rod 3|provide the latter with end shoulders which engage the inner surfaces ofthe opposite cars 28, so that said rod is held against longitudinalmovement although free to rotate. The upper end of the rod 30 isprovided with means by which it may be engaged by a suitable tool toeffect rotation thereof. For

purposes of illustration and without intending to limit the invention, aslot 32, to be engaged by a screw driver is shown for this purpose. v

In practice, the plate 20, frame-carrier member 21 and the screw 3| areassembled in the relation shown in the drawing, and the frame-carriermember of each mounting A is spot welded or otherwise attached to a sideof the frame F, in the manner hereinabove described. When it is desiredto install a door frame F, lugs 25 are engaged with the strips H5 at theapproximate horizontal plane to be occupied by the lower edge of theplate 20. As the frame F is inserted into the front opening of thecabinet C, one of the notches 24 of each plate 20 is engaged with itslug 25. In this manner each plate 20 is removably anchored to its endwall I2, and the two plates will sustain the weight of the frame at theopposite ends of the latter. After the frame mounting is so installedrelative pivotal movement of the frame-carrier 21 and the supportingplate 20 is prevented; In this connection, it is to be understood thatthe lug 25 will be engaged with a selected notch 24 which will placetheframe F in such a position that its front face will be in alignmentwith the front outer edge of the adjacent end wall l2. Then by rotatingthe shaft 7 3|, the reaction member 2'! will be caused to travelupwardly or downwardly, according to the direction of rotation of therod 3!, so as to correspondingly adjust the frame F to its requiredjuxtaposition with respect to the under face of the top H of the cabinetC. It is contemplated that molding M will be removably attached tothe'front edges of the end walls 12 of the cabinet unit container, andso positioned as to overlap the ends of the frame F after its finalpositioning in the manner illustrated in a pending application SerialNumber 455,481,

The advantages of the invention will be readily understood by thoseskilled in the art to which it belongs. For instance, it will beobserved that a very simple and inexpensive door-frame mounting isprovided for a store furniture unit, which mounting is capable of firmlysupporting said frame in its operative position. An important advantageis that accurate location of the door frame with respect to the cabinetopening is assured, because of the possibility of readily adjusting theposition thereof after its initial installation. Another advantage isthat the mounting is so constructed and arranged that it permits ofquick installation of the door frame, or ready removal thereof, asoccasion may require.

If; is to be understood that although only two I frame mountings A havebeen shown and described, the invention is not limited in thisparticular, because any desired number may be used, depending upon thesize of the door frame to be installed.

Having thus explained the nature of the invention and described anoperative manner of constructing and usin the same, although withoutattempting to set forth all of the forms in which it may be made, or allof the forms of its use, what is claimed is:
